Field Detail

baseURL

public java.lang.String baseURL

The URL used for the tile requests.

Supported formats:

• The base part of the URL, for example 'http://tile.openstreetmap.org'. This results in an URL like 'http://tile.openstreetmap.org/12/123/456.png'.
• An URL template with the placeholders '{x}', '{y}' or '{-y}', and '{z}'. For example: 'http://tile.openstreetmap.org/{z}/{x}/{y}.png'.
  The placeholder '{-y}' provides support for OSGeo TMS tiles.

maxExtent

public double[] maxExtent

The maximum extent of the osm layer. Must have 4 coordinates, minX, minY, maxX, maxY

Default: [-20037508.34, -20037508.34, 20037508.34, 20037508.34]

tileSize

public int[] tileSize

The size of each tile. Must have 2 values: width, height

Default: [256, 256]

resolutions

public java.lang.Double[] resolutions

The allowed resolutions for this layer.

resolutionTolerance

public double resolutionTolerance

The amount of difference between a resolution and a target resolution to consider the two equal. The value is a value from 0-1.

dpi

public java.lang.Double dpi

The DPI of the OSM tiles.

Method Detail

postConstruct

public void postConstruct()
                   throws java.net.URISyntaxException

Validate the properties have the correct values.

Throws:

java.net.URISyntaxException

getMaxExtent

public com.vividsolutions.jts.geom.Envelope getMaxExtent()

Get the max extent as a envelop object.

getBaseUrl

public java.lang.String getBaseUrl()

Description copied from class: AbstractTiledLayerParams

Get the base url for all tile requests. For example it might be 'http://server.com/geoserver/gwc/service/wmts'.

Specified by:

getBaseUrl in class AbstractTiledLayerParams

getTileSize

public java.awt.Dimension getTileSize()

createCommonUrl

public java.lang.String createCommonUrl(com.google.common.base.Function<com.google.common.collect.Multimap<java.lang.String,java.lang.String>,com.google.common.collect.Multimap<java.lang.String,java.lang.String>> function)

Description copied from class: AbstractTiledLayerParams

Create a URL that is common to all image requests for this layer. It will take the base url and append all mergeable and custom params to the base url.

Specified by:

createCommonUrl in class AbstractTiledLayerParams

Parameters:

function - a function that can optionally modify the Multimap passed into the function and returns the Multimap that will contain all the query params that will be part of the URI. If the function returns null then the original map will be used as the params.

validateBaseUrl

public boolean validateBaseUrl()

Description copied from class: AbstractTiledLayerParams

Validates the provided base url.

Specified by:

validateBaseUrl in class AbstractTiledLayerParams

Returns:

True, if the url is valid.
